If John is hanging posters for the class election...and I am hanging posters for the class election...how do we combine these into a single sentence?

The answer is:

John and I are hanging posters for the class election.

  • But why?

There are three main rules to remember when dealing with compound nouns.

  1. If the nouns are joined by the word and, use a plural verb.

When you use and, it signals addition.

In the example above, John and I are both hanging the posters. Whether or not both of us are hanging them together, the action is describing what both nouns are doing as a single event.

Here's another example:

Spike runs after the ball.
Chomps runs after the ball.
Bowser runs after the ball.

Spike, Chomps, and Bowser run after the ball.

All three subjects are performing the verb; therefore, it is plural.

  1. If singular nouns are joined by the word or or nor, use a singular verb.

In cases where or or nor is being used, it makes a distinction in who is performing the verb or how the verb will be performed.

If there are only enough posters for one person to hang, for example, than either John or I might hang them, but not both.

Take a look at the difference:

Either John or I is hanging posters for the class election.

When the hanging is completed, only one of the two subjects will have completed it. Therefore, a singular noun is used.

  1. If a singular and plural noun are joined by the word or or nor within the compound noun, the verb should agree with the noun closest to it.

Here's an example:

Patrice or the cheerleaders are responsible for that part of the project.

The cheerleaders or Patrice is responsible for that part of the project.

The verb still indicates who will have completed the action once it is done; therefore, the assumption is that the subject completing the action is the one closest to the verb.
